However, population and development are expected to transform it into a compact urbanizeci corridor. Valley open space suitable for recreation will consequently be lost. - 2 Today, innovative planning, design and acquisition policies together with the rapid urban growth patterns, traffic corridors, and development pressures have played a decisive role in the recent definition of the Park. With the Coyote, extensive open space and park lands are utilized as the major spine of the Park, with roads, automobiles and urban noise buffered at the edges and crossings. A major design concept involves replace ment of park roads for pleasure driving with a compre hensive equestrian, bicycle and walking trails system. Supplementing these trails will be motorized tram cir- - cuits, carriage rides and other systems as needed to move families and groups of visitors to recreation areas throughout the park without the accompanying noise or congestion of the family automobile. These varied inter-park systems, with future connection to public rapid transit, will provide an economical mode of per sonal transportation throughout the park. The design of scenic streets, serving adjacent resi dential and urban developments at the Park's perimeter, provide excellent opportunities for continuous viewing and driving along the park. Access roads to the major recreation area within the Park are also served by roads and expressways crossing the site. Along the Diablo foothills, the proposed South Valley Freeway will be providing travelers with a range of scenic views into and across the adjacent Park. Le gislative approval of this freeway as a scenic highway, together with protection of the hillside visual corridor, are necessary steps to the development of a compre hensive park system which meets the recreation, trans portation and open space needs of the region. 3 Flood Plain Development SITE CHARACTERISTICS Urban Development The visual site character of the Coyote Creek Park is An effect of urban development on the foothills will be separated into two general areas as follows: the increase in surface water runoff and changes in groundwater conditions.
